SPECIFICATION forming part of Letters Patent N 0. 793,733, dated July 4, 1905.

Application filed August 31, 1904. Serial No. 222,863.

To all; whom, it may concern.-

Be it known that I, JOHN P. MULLER, a citi- Zen of the United States, residing at Freeport, in the county of Stephenson and State of Illinois, have invented a new'and useful VVindmill, of which the following is a specification.

This invention relates to windmills.

The object of the invention is to present a windmill having a novel arrangement of pitman-rod-actuating and vane-controlling mechanism, all of the parts being constructed and combined in such manner as to reduce the number of elements employed to a minimum, with the least weight to secure the greatest strength, to render repairs easy of accomplishment, to minimize liability of breakage, and generally to improve the operative mechanism of a windmill of the character hereinafter described.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a windmill, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements-therein exhibited may be varied or changed as to shape,

proportion, and exact manner of assemblage without departing from the spirit thereof.

In the drawings, Figure 1 is a view in elevation exhibiting the parts of the windmill when the same is out of the wind. Fig. 2 is a view in plan exhibiting in full lines the position of the vane when the wheel is out of the wind and in dotted lines its position when the wheel is in the wind. Fig. 3 is a sectional detail view of a portion of the vane, showing more particularly the mechanism for limiting its movement in both directions. Fig. 4 is a sectional detail view of a portion of the vane and certain mechanism coacting therewith. Fig. 5 is a view in elevation,

limit in one direction. Fig. 6 is a detached detail view of one of the blades, showing the manner in which it is adjustably connected with its rings. Fig. 7 is a fragmentary detail View showing the brake mechanism combined with the vane-casting for stopping the rotation of the wheel. Fig. 8 is an enlarged detail view of the wheel-spider.

Referring to the drawings, 1 designates the frame-bars for supporting the operative mechanism of the windmill, the same being herein shown as constructed of angle-iron and as four in number, it being understood, of course, that this number may be increased if found necessary or desirable. Upon the upper ends of these bars is secured the roller-ring 2, which, as clearly shown in Fig. 5, is an annulus, the rollers 3 of which are disposed near its periphery. The rollers are disposed below the upper edge of the ring in order to keep the turntable 4 in cooperative relation with the rollers. The turn-table is provided with a central orifice through which projects the main tube 5, in which works the pump-rod 6, the lower end of which connects with the pump in the usual or any preferred manner. The tube is provided at one side with a longitudinal slot 7, through which projects the lower end of the pitman-rod 8, and is connected with the pump-rod by a pivot 9. (Indicated by dotted lines in Fig. 1.) The upper end of the pitmanrod is connected with a wrist-pin 10,.carried by a gear-wheel 11, mounted upon a stub-shaft 12, working in ajournal-boX 13, carried by the turn-table, the upper member of the journalbox being provided with an oil-cup 14, as usual, and being secured to its lower member through the medium of bolts 15, the lower member being preferably integral with the turn-table. The gear-wheel 11 meshes with a pinion 16, carried by the wheel-shaft 17, the said shaft being mounted in a journal-bearing 18, the lower member of which is by preference integral with the turn-table and the upper memberbeing combined therewith through the medium of bolts 19, the said upper member having an oil-cup'20, as usual.

Upon the shaft 17 is mounted a wind-wheel, (designated generally 21,) which consists of a plurality of blades 22 of any preferred contour and combined with wheel-rings 23 and 24, which by preference are made in sections and bolted or otherwise connected with the wheelspokes 24, of which there may be any preferred number, in this instance four, the inner ends of the spokes being secured in a spider 25, keyed or otherwise secured to the wheelshaft. T he shaft 17 projects beyond the spider 25 and carries at its outer end, a second spider 26, which connects the inner ends of the wheelbraces 27, the outer ends of which are connected in any preferred manner with the spokes 24*. In order to vary the pitch of the blades with relation to the rings, there is provided a novel form of adjusting mechanism therefor, comprising a plate 28, which is riveted or otherwise secured to the rear side of each blade and is provided with a lug 29, which is pivotally connected with the ring 24, as clearly shown in Fig. 6. The plate further carries near one end a curved arm 30, provided with a plurality of orifices 31, and these orifices are designed to be engaged by a bolt or rivet .32, secured in any suitable manner to the ring 24. It will be seen that by removing the bolt 32 the blade may be pitched at any desired angle with relation to the ring and be held at this adjustment. As herein shown, there are but three orifices provided in the arm 30;. but, as will be obvious, this number may be increased to extend the range of adjustment of the blades, and as this will be understood detailed illustration is omitted. The inner ends of the blades are connected with the ring 23 through the medium of astem 33, the end of which passes through the ring and is held combined therewith by nuts 34, disposed on the opposite sides of the ring.

The turn-table is provided eccentrically of the tube-orifice with a hollow boss 35, Fig. 4, in which is loosely mounted one end of a section of tubing 36, constituting the vane-standard, and upon this standard and adjacent to the boss is a vane-stop 37, the same consisting of a collar held combined with the standard by a bolt 38 and provided with two lugs 39 and 40, Fig. 3, which are adapted alternately to engage with a stop 41, integral with or secured to the turn-table 4. Disposed above the vane-stop is a vane-casting comprising a collar 42 and a tubular extension 43, projected at right angles to the collar, the collar being held against rotation upon the standard by a jam-bolt 44. The extension 43 receives the shank'45 of the vane 46, which may be of any desired construction, the shank being held combined with the extension by a jam-bolt 47 To hold the standard against any lateral the vane in position to keep the wheel in the wind, there is provided a spiral or coil spring 51, through which extends a rod 51, the lower terminal of which projects through the turntable 4 and carries a nut 51 for clamping it in position, a pin or stop 51, projecting through the rod and bearing upon the upper side of the turn-table, serving to prevent the rod from being drawn therethrough. The lower terminal of the spring is secured to the rod by a bolt 51, and its upper terminal projects through a slot 52 in the vane-standard 36. the tension of the spring 51, the nut 51" will be loosened and the rod turned by any suitable implement until the spring is placed under the requisite tension, and the nut is again tightened, thereby positively holding the rod against rotation. It will be seen from this construction that when the vane is turned to the position shown in full lines in Fig. 2 the spring will be placed under tension and that when the vane isreleased the spring will cause it automatically to resume a position at right angles to the face of the wheel, as shown by dotted lines in Fig. 2. To effect turning of the vane-standard, and with it the vane, there is provided a chain-casting 53, clearly shown in F1g. 2, the same comprlslng a flanged curved arm mounted upon the upper end of the vane-' standard and held combined for rotation therewith by a jam-bolt 54. To the upper side of the outer end of the casting is secured in any suitable manner, as by a bolt 55, one end of a chain 56, the free portion of whichis passed over a sheave 57, carried by a casting 58, mounted upon the upper endof the tube 5,

Should it be desired any time to increase and thence down into the tube, the depending ground. It will be seen that upon draft being applied to the rope 59 the casting 53 will be moved at right angles to its normal position, thereby bringing the vane to the proper position to hold the wheel out of the wind. When the parts are in this position, the rope will be held against loosening by being wrapped around a cleat or combined with any other holding device; but immediately upon being released the spring 51 will then perform its function and cause the vane to return to the position shown by dotted lines in Fig. 2. The sheave-casting, to which reference has been made, comprises a collar 61, suitably secured to the upper end of the tube and provided with a pair of ears 62, between which the sheave is journaled. In order to cause the wheel to be checked automatically when thrown out of wind, the vane-casting 42 has combined with it a lug 63, as shown in Fig. 7, and this is designed to engage a springbrake 64:, which latter partially encircles a roller 65, carried by the wheel-shaft 17, the lower end of the spring 64 being secured in anysuitable manner to the turn-table. While this form of brake mechanism is exceedingly simple in construction, it will be found thoroughly effective in use and in case of damage or breakage may readily be replaced.

From the foregoing description it will be seen that although the machine of this invention is exceedingly simple in construction it combines in a practical and feasible manner all the elements necessary to produce a thoroughly-effective machine and, further, that provision is made for ready repairs should the necessity therefor arise.

Having thus fully described the invention, what is claimed is- 1.
